Abstract
A nuclear radiation shielding alloy lead fiber woven fabric relates to the field of nuclear radiation protection biological shielding technology and is particularly applicable to the technical field of core materiasl for the production of nuclear radiation biological protection flexible shielding products. According to the nuclear radiation shielding alloy lead fiber woven fabric, nuclear radiation shielding alloy lead fiber yarns with the diameter of 0.01 mm-1 mm are arranged in the weft direction, and nuclear radiation shielding alloy lead fiber yarns with the diameter of 0.001 mm-1 mm and glass fiber yarns with the diameter of 0.05-0.5 mm are arranged in the warp direction. The nuclear radiation shielding alloy lead fiber woven fabric not only has a certain function of shielding nuclear radiation, but also ensures the weaving process to proceed smoothly by adopting the glass fiber yarns, meanwhile, the tensile strength of products is improved, and the follow-up production of light, thin and material-saving nuclear radiation shielding products is facilitated.
Description
Technical field
The present invention relates to nuclear radiation protection biological shielding technology, particularly be applied to nuclear radiation biological protection flexible shielding production of articles inner core and use the material technical field.
Background technology
Research shows; The external exposure line of nuclear power station is mainly gamma-rays, and it is mainly from the fission product of nuclear reaction with by the pipeline of neutron activation and valve, because the appearance of activation corrosion product in the pipeline; Cause the deposition of radioactive particulate in the pipeline; Make control zone a lot of upkeep operation site surrounding dosage higher, increased staff's external irradiation dose, general employing shielding is removed.Therefore, on shielding material is selected, make every effort to highly effective and safe, inexpensive and save the space, select steel, lead, normal concrete and loaded concrete etc. usually.The intensity of steel is better, but price is higher; Concrete is more cheap than heavy metal, but density is little, and shielding thickness is big; Plumbous advantage is that density is high, fusing point is low, anti-corrosion, gamma-rays is had good adsorption property and is difficult for by through characteristic, is easy to cast and shielding thickness is less relatively, so lead is first-selected shielding material.
At present; In the nuclear power station of operation; The shielding goods (plumbous clothing or lead shield) that control zone biological shielding system adopts mainly are: " the no gap solid metal block shape stereotype " of roll forming, this metal stereotype exist that lead equivalent is low, conformal performance can be poor, the generation waste material is many, resource utilization is not high; Product is heavy, and it is big to cause shielding operation labor intensity, and staff's exposure time is long, dosage is big; Be prone to cause heat-insulation layer distortion, tenesmus, the control zone roentgen dose X increases, and safety coefficient is low, and potential risk is big; Be not suitable for special-shaped equipment such as pipeline, valve and personnel's shielding; And be difficult for decontamination, drawback such as service life is short.Therefore, stereotype shielding goods are difficult to compatibility, sustainable development of incompatibility nuclear industry and the needs that people-oriented on shield effectiveness and structure function.
Research shows that anti-nuclear radiation biological shielding goods also must possess good physical and mechanical property (obdurability, heat endurance etc.) except that will having higher shield effectiveness.It is reported that current, the material and the goods that are used for anti-nuclear radiation biological shielding mainly contain following four types.One type is that to use lead with general industry be main, the no gap metal derby shape stereotype of roll extrusion or moulding by casting, lead brick, sheet lead concrete etc.; Second type is to be main with lead powder, and rubber, polyethylene foam etc. are as the coating of the mixed flexible article that is composited of base-material, adhesive etc.; The 3rd type be with no gap metal derby shape sheet lead as inner core, ectonexine coats crosslinked foaming material and synthetic rubber polyamide fibre material product; The 4th type is to make light-weight high-strength materials such as cenosphere with heavy metals such as lead.Facts have proved that although stereotype, the anti-nuclear radiation effect of sheet lead goods are preferable, use amount is big when building shielding harness, it is big to build difficulty, inefficiency, and it is many to produce waste material, and potential risk is big; And stereotype goods conformal performance is poor, can not bend, and is not suitable for the shielding of special type equipment such as pipeline, valve, and careless manipulation is prone to drop and hurts sb.'s feelings or damage equipment.And mixed goods, coating and the adhesive that is composited of lead powder and rubber, polyethylene foam-material; Though have certain flexibility,, be difficult in base-material evenly mixed because the lead powder particle is prone to gather; So shielding properties is inhomogeneous; And lead equivalent is low, rubber and polyethylene etc. are prone to agingly, influences shield effectiveness, brings by the danger of radiation to the staff.The cenosphere light-weight high-strength material that heavy metals such as lead are made, though anti-nuclear radiation performance is excellent, cost is high, cost is big, generally is used for the anti-nuclear radiation of nuclear rocket engine and leaks.
Summary of the invention
The object of the invention is to propose a kind of lightweight, the plumbous fibre fabric of intensity nuclear radiation shield alloy high, good uniformity.
Broadwise of the present invention is that diameter is 0.01mm～1mm nuclear radiation shield alloy lead fiber silk, and warp-wise is that 0.01mm～1mm nuclear radiation shield alloy lead fiber silk and diameter are that the glass fibre silk thread of 0.05～0.5mm is formed by diameter.
Per 3～7cm is provided with said glass fibre silk thread in said warp-wise.
The present invention is a broadwise with nuclear radiation shield alloy lead fiber silk; With nuclear radiation shield alloy lead fiber silk and glass fibre silk thread is that warp-wise is weaved; The product that forms not only has certain shielded nucleus radiation function; Also, can guarantee carrying out smoothly of weaving process, also improve the tensile strength of product owing to adopted the glass fibre silk thread; Be beneficial to that subsequent production is light, thin, the anti-nuclear radiation product in material-saving type, like goods such as " shielding protection clothes ", " soft lead screen ", " refined lead curtain ", " safety shoe ", " radiating the pipeline housing ".
The specific embodiment
Cut-off directly is around on the cop of weaving usefulness for 0.01mm～1mm nuclear radiation shield alloy lead fiber silk.
Cut-off is that the glass fibre silk thread of 0.05～0.5mm passes for 0.01mm～1mm nuclear radiation shield alloy lead fiber silk and diameter directly, and controls per 3～7cm and be provided with a glass fibre silk thread.
Weave the plumbous fibre fabric of formation nuclear radiation shield alloy through loom.
Claims (2)
1. the plumbous fibre fabric of nuclear radiation shield alloy; It is characterized in that broadwise is that diameter is 0.01mm～1mm nuclear radiation shield alloy lead fiber silk, warp-wise is that 0.01mm～1mm nuclear radiation shield alloy lead fiber silk and diameter are that the glass fibre silk thread of 0.05～0.5mm is formed by diameter.
2. according to the plumbous fibre fabric of the said nuclear radiation shield alloy of claim 1, it is characterized in that per 3～7cm is provided with said glass fibre silk thread in said warp-wise.
